We recently synthesised a new compound, K2Ni2(SO4)3, that allows the existence of non-trivial topologicalphases such as skyrmions. Specific heat measurements show the existence...

Lanthanide coordination frameworks containing polyatomic anions are attracting increasing attention for low dimensional magnetism, which appears to be linked to improved...

Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This...

In our previous experiments we have investigated the surface properties of liquid 3He - 4He mixtures by neutron reflection. We have shown that in broad temperature range there...

Systems with antiferromagnetic ordering that is driven predominantly by dipolar interactions are very rare, as the dipolar interaction is inherently weak compared to the...

Usually, magnetic materials can be understood by imagining them as orderly rows of communicating, atomic-sized bar magnets (or "spins") which organize themselves into a...

In BaDy2O4, the magnetic Dy3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, which gives rise to geometric...

We have observed an interesting phenomenon of the destruction of long-range magnetic order in SrEr2O4 by a relatively modest applied magnetic field. For a field applied along...

We propose to use neutron diffraction to establish the magnetic structure of D-type of Er2Si2O7 in zero field first with a view of extending the measurements to an applied field...

Dy3Mg2Sb3O14 forms a layered structure with magnetic Dy3+ ions forming sheets of corner sharing triangles, called a Kagome lattice. The Ising magnetic moments are constrained to...

Iridium oxides are of interest because many novel magnetic phases have been predicted in crystals, depending on the geometry of the crystal lattice. Our proposal concerns one...

In our recent experiment RB1120146 we have obtained new exciting results on neutron scattering on liquid He surface. At 1.5 and 2.3K there was no difference in reflectivity...

We propose to investigate the resonance peak in superconducting CeCoIn5 as a function of applied field. Preliminary low resolution cold triple-axis data has been suggestive that...

This proposal would like to map the diffraction patterns of Gd3Al5Gd12 (GAG) using the high flux diffraction instrument WISH. It is of great interest to solve the magnetic...

Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3...

The material Cu(1,3-benzenedicarboxylate) (C8H4CuO4) features structurally perfect kagome lattice planes of spin-1/2 copper2+ ions, with the separated by organic linkers. High...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

We propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the...
